Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage engineering, in particular to a robot for pipe network detection. Background Art

[0002] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they serve the purpose of drainage, they should be counted as drainage pipes.

[0003] The Chinese invention patent with publication number CN115978350A disclosed a pipeline robot on April 18, 2023, including a frame, multiple walking components, a driver and multiple transmission components, wherein the walking components are arranged on the frame, and the multiple walking components are arranged at intervals along the circumference of the frame, and the spacing between the walking components and the frame is adjustable to adapt to different pipe inner diameters; the driver is arranged on the frame, and the multiple transmission components are connected one by one between the multiple walking components and the driver, so that the driver can drive the multiple walking components to move synchronously at the same time. The pipeline robot of the embodiment of the present invention has the advantage of high walking consistency.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing pipeline inspection robots are large in size, heavy in weight, and have a complex structure, which makes it impossible to miniaturize and enter small-diameter drainage pipes, making it impossible to inspect small pipes. At the same time, the heavy robot is difficult to move in the pipes full of dirt, resulting in low movement efficiency. Utility Model Content

[0005] The utility model aims to solve the technical problems that the existing pipeline inspection robots are large in size, heavy in weight and complex in structure, making it impossible to miniaturize and enter into drainage pipes with small diameters, making it impossible to inspect small pipes, and at the same time, the heavy robots are difficult to move in pipes full of dirt, resulting in low movement efficiency, and provides a robot for pipeline network inspection.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A pipeline inspection robot described in the utility model comprises an I-shaped plate; four positioning pins are inserted on the I-shaped plate; a support sleeve is sleeved on the positioning pin; a support plate is inserted into a hole at the upper end of the support sleeve; a motor is fixedly connected to the upper end of the support plate; a roller is fixedly connected to the shaft of the motor; an external pin is pinned on the lower end of the support sleeve; a pin seat is sleeved on the external pin; a threaded slider is pinned on the pin seat; the threaded slider is symmetrically threadedly sleeved on symmetrical threaded rods; the symmetrical threaded rods are inserted in the grooves of the I-shaped plate; a clamping plate is fixedly connected to the I-shaped plate corresponding to the symmetrical threaded rods; and inspection cameras are fixedly connected to both sides of the I-shaped plate.

[0008] Furthermore, a bolt is threadedly inserted into a hole on the outer surface of the support sleeve; a mouth plate and an elastic member are slidably sleeved on the bolt; a protrusion is fixed on the mouth plate; the protrusion is inserted into a slot; and the slot is provided in the support plate.

[0009] Furthermore, the support sleeve and the support plate are made of aluminum alloy tubes.

[0010] Furthermore, the I-shaped plate is made of engineering plastics.

[0011] Furthermore, the symmetrical threaded rod and the threaded slider are made of stainless steel.

[0012] The utility model provides a pipe network detection robot, which has the following beneficial effects:

[0013] 1. The utility model changes the distance between the two rollers by changing the distance between the support plate in the support sleeve, and then rotates the symmetrical threaded rod, so that the two threaded sliders move away from or close to each other, thereby pulling the angle between the two support sleeves, so that it can adapt to drainage pipes of different diameters, and the inspection robot can be connected to the central part of the drainage pipe by rolling horizontally to move forward and backward without contacting with the dirt under the pipe to cause deceleration and damage. With the upper and lower inspection cameras, the upper and lower halves of the drainage pipe can be visually inspected, thereby achieving adaptation to drainage pipes of different diameters, solving the problem that the existing visual inspection robot is large in size and cannot adapt to drainage pipes of different diameters and is heavy enough to cause damage due to contact with dirt;

[0014] 2. The utility model compresses the elastic part by pressing the mouth plate, so that the mouth plate moves on the support plate, and the protrusion is pushed out of the slot. At this time, the support plate can be pulled to change the position of the roller to adapt to drainage pipes of different diameters. Then the mouth plate is released, and under the elastic force of the elastic part, the protrusion is inserted into the slot to complete the locking between the support sleeve and the support plate. By adjusting the distance between the support sleeve and the support plate, the roller is matched to stably support the drainage pipe, so as to adapt to drainage pipes of different diameters for horizontal suspended support. Therefore, under the visual inspection of two inspection cameras, the inner walls of the upper and lower parts of the drainage pipe can be visually inspected, and it will not contact with the dirt in the lower half of the pipe to cause pollution, which solves the problem that the existing inspection robot is heavy and can only move in the lower half of the drainage pipe for inspection, which will be contaminated.

In conjunction with the upper and lower inspection cameras 17, the upper and lower halves of the drainage pipe can be visually inspected, thereby achieving adaptation to drainage pipes of different diameters, solving the problem that the existing visual inspection robot is large in size and cannot adapt to drainage pipes of different diameters and is heavy enough to cause damage due to contact with dirt.

[0024] The outer surface of the support sleeve 3 has a threaded hole with a bolt 7 inserted therein; a mouth plate 8 and an elastic member 9 are slidably sleeved on the bolt 7; a protrusion 10 is fixedly connected to the mouth plate 8; the protrusion 10 is inserted into a slot 11; the slot 11 is provided in the support plate 4; when working, the mouth plate 8 is pressed to compress the elastic member 9, so that the mouth plate 8 is displaced on the support plate 4, and the protrusion 10 is pushed out from the slot 11. At this time, the support plate 4 can be pulled to change the position of the roller 6 to adapt to drainage pipes of different diameters, and then the mouth plate 8 is released. Under the elastic force of the elastic member 9, the protrusion 1 0 is inserted into the card slot 11 to complete the locking between the support sleeve 3 and the support plate 4. By adjusting the spacing between the support sleeve 3 and the support plate 4 and cooperating with the roller 6, it is stably supported in the drainage pipe, so as to adapt to drainage pipes of different diameters for horizontal suspended support. Therefore, under the visual inspection of the two inspection cameras 17, the inner walls of the upper and lower parts of the drainage pipe can be visually inspected, and it will not contact with the dirt in the lower part of the pipe to cause pollution, which solves the problem that the existing inspection robot is heavy and can only move in the lower part of the drainage pipe for inspection and will be contaminated.

[0025] The support sleeve 3 and the support plate 4 are made of aluminum alloy tubes. When working, the support sleeve 3 and the support plate 4 made of aluminum alloy tubes can maintain lightness while maintaining sufficient supporting strength, thereby reducing the driving pressure of the motor 5 and increasing the moving speed of the detection robot. Therefore, mobile detection can be performed quickly in the drainage pipe, thereby improving the efficiency of mobile detection and solving the problem of low efficiency of existing crawler detection robots.

[0026] The I-shaped plate 1 is made of engineering plastics. When working, the I-shaped plate 1 is made of engineering plastics, so that the structure strength is sufficient and the lightness is sufficient, and it is waterproof and rust-proof, and can be used for a long time.

[0028] By adopting the above scheme, when the utility model is in use, the distance between the two rollers 6 is changed by changing the distance between the support plate 4 in the support sleeve 3, and then the symmetrical threaded rod 15 is rotated, so that the two threaded sliders 14 move away from or close to each other, thereby pulling the angle between the two support sleeves 3, so that drainage pipes of different diameters can be adapted, and the inspection robot can be connected to the central part of the drainage pipe by rolling horizontally to move back and forth without contacting the dirt under the pipe to cause deceleration and damage. With the upper and lower inspection cameras 17, the upper and lower halves of the drainage pipe can be visually inspected, thereby achieving adaptation to drainage pipes of different diameters, solving the problem that the existing visual inspection robot is large in size and cannot adapt to drainage pipes of different diameters and is heavier than the dirt and causes damage; by pressing the mouth plate 8 to compress The elastic member 9 causes the shaped plate 8 to move on the support plate 4, and the protrusion 10 is pushed out from the slot 11. At this time, the support plate 4 can be pulled to change the position of the roller 6 to adapt to drainage pipes of different diameters, and then the shaped plate 8 is released. Under the elastic force of the elastic member 9, the protrusion 10 is inserted into the slot 11 to complete the locking between the support sleeve 3 and the support plate 4. By adjusting the distance between the support sleeve 3 and the support plate 4, the roller 6 is matched to stably support the drainage pipe, so as to adapt to drainage pipes of different diameters for horizontal suspended support. Therefore, under the visual inspection of the two inspection cameras 17, the inner walls of the upper and lower parts of the drainage pipe can be visually inspected, and it will not contact with the dirt in the lower half of the pipe to cause pollution, which solves the problem that the existing inspection robot is heavy and can only move in the lower half of the drainage pipe for inspection, which will be contaminated.
